Coders In C

Hey Guys, welcome to Flutter Blog. In this blog, i have created a simple example that can check whether App is installed on the device. If yes then open a Particular app with a link / URL. In my blog, it is a video link and opening that link with MX player. Also, I have checked the VLC player that is not installed on my system.

In Android Kotlin / Java this can be done using Intent. In flutter we can fire the same intent with data. Checkout this Video Demo of OutPut.

Here you can see i have created to option that opens a link with MX player or VLC player. You can play the video with a selected Video Player.

Let’s start developing,

First we need to add some dependencies in pubspec.yaml file

dependencies:
  url_launcher:
  device_apps: ^2.1.1
  android_intent:
  flutter_appavailability: ^0.0.21
  intent: ^1.4.0

run Flutter pub get Command

after that copy this function and pass required app package names

Future<void> openLink(String url) async {
    try {
      // await canLaunch(url) ? await launch(url) : throw 'Not Open url';
      print(packegeNames[0]);
      var p = "";
      if (selectedPlayer == players[0]) {
        p = packegeNames[0];
      } else if (selectedPlayer == players[1]) {
        p = packegeNames[1];
      }
      bool isInstalled = await DeviceApps.isAppInstalled(p);
      print("is ::$isInstalled");
      if (isInstalled) {
        setState(() {
          msg = "App Found";
          android_intent.Intent()
            ..setAction(android_action.Action.ACTION_VIEW)
            ..setData(Uri.parse(url))
            ..setPackage(p)
            ..startActivity().catchError((e) => print(e));
        });
      } else {
        msg = "App Not Found";
        setState(() {});
      }
    } catch (e) {
      print("url not open ");
    }
  }

here packegeNames[0] is an array that contains the package names of applications that we want to check is installed or not and if installed open with URL to play that video.

This is How i designed List view for Application Options

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text("Link Example")),
        body: Column(
          children: [
            Expanded(
              child: ListView(
                children: [
                  Padding(
                    padding: const EdgeInsets.all(18.0),
                    child: Text("Open With"),
                  ),
                  ListTile(
                    title: Text(players[0]),
                    trailing: Checkbox(
                        value: isPlayerSelected[0] == 1 ? true : false,
                        onChanged: (value) {
                          
                        }),
                  ),
                  ListTile(
                    title: Text(players[1]),
                    trailing: Checkbox(
                        value: isPlayerSelected[1] == 1 ? true : false,
                        onChanged: (value) {
                          
                        }),
                  )
                ],
              ),
            ),
            Text(msg),
            ElevatedButton(
              onPressed: () {
                print('selected player : $selectedPlayer');
               
              },
              child: Text("Open Url"),
            ),
            Spacer(),
          ],
        ),
      ),
    );
  }
}
